WDT-3 Static Flexibility Test Machine for Flexible Cables – Compliant with IEC 63294, IEC 60245-1, and IEC 60227-1 Standards

The WDT-3 Static Flexibility Test Machine is engineered for conducting static flexure tests on finished flexible cables as part of mechanical strength evaluations. During testing, a cable sample of specified length is secured at the clamping ends. Following the establishment of the initial clamping distance, one end is displaced to form the cable into a standardized U-shape configuration. The test procedure concludes with the measurement of the final distance between the clamping ends. This apparatus is specifically designed for flexible cables with defined structural and dimensional parameters. It is not applicable to cables whose conductor nominal cross-sectional areas or concentric layers exceed the designated range, thereby ensuring standardized testing conditions for verifying the mechanical performance compliance of flexible cables.

Standard:

Specification:
• Flexural length: 200 -1500(mm)
• Sample outer diameter: φ6 – 32(mm)
• Sample length: 3000±5% (mm)
• Height above ground: 1500mm
• Overall dimensions (length*width*height): 2000*400*1800mm

Applications:
1. Static bending mechanical strength testing of rubber-insulated finished flexible cables in accordance with IEC 60245-1 and GB/T 5013 series standards;
2. Static bending performance verification of PVC-insulated finished flexible cables compliant with IEC 60227-1;
3. In-process and final quality control inspections by cable manufacturers for flexible cables within the specified application scope;
4. Third-party certification and compliance testing of the mechanical performance of flexible cables against international and national standards;
5. Research and development optimization testing for the static bending performance of flexible cable products.
